Historical statistics for July 2025 to June 2026, not live status. For today’s DL 312, check with Delta Air Lines.

DL 312 lands a B, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 3 minutes early.

Set against the rest of the country, DL 312's record is 5 points better than the US average of 77.6%. That gap is worth roughly 49 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 3 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When DL 312 flies

DL 312 flies MSP to HNL without a single fixed slot. Its most common scheduled departure was 10:10, used on 99 of 365 flights, with 10:15 (95 flights) and 10:05 (46 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 10:10 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 312 runs level with that at 82.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

DL 312 quarter by quarter

DL 312 did not run the same all year. Its best quarter was Apr–Jun 2026 at 92.3% on time and its weakest Jan–Mar 2026 at 69.7%, a swing of 23 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Jul–Sep 202592 flights90.9%
Oct–Dec 202592 flights76.9%
Jan–Mar 202690 flights69.7%
Apr–Jun 202691 flights92.3%

Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 312 ranged from 75.0% on Saturday to 86.5% on Thursday. With about 52 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 312 runs late

One category carries most of the weight here. Carrier accounts for 72% of the 5,015 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier
72%
National Airspace System
21%
Late-arriving aircraft
3%
Extreme weather
3%

The largest share of delay minutes, 72%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 3,627 of the 5,015 delay minutes reported here. The split is drawn from 5,015 delay minutes reported on DL 312.

Cancellations sit at 1.37% against a national 1.81%, which is ordinary. Diversions add another 0.27%.

Connections and routes

What a delay on this flight costs

6.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

At 3,972 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

Every one of the 365 flights under DL 312 in the data flew MSP to HNL. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 365 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
